DIY Sony VFET Builders thread

I'm no electrical engineer, nor any sort of a wizard. Merely an enthusiast that takes most of my cues from all of you. That was the response I received from Nelson. Which alludes there probably isn't a problem if you don't connect it. At this point if I don't have to get my fat fingers in there to add it... it would be a blessing.

Color me confused. So are we to interpret the last several posts as to leave the tabs unconnected?

Also, are we supposed to make the filter PCB corner with the thermistor the “chassis safety earth,” as in file the surface of the bottom plate and make an earth connection there? Or is that not needed with the external single voltage SMPS?

I’m more than happy to keep it simple.

@dudeisms - I'm absolutely, definitely, most-assuredly no expert.

My WAG is that it won't manifest itself it a blowy-uppy-your-ampy kinda way if the wiring is added either. I just think it's curious. :)

Also, since I happened to have 3 out of 4 prototype boards ... and I'm a bit of a novice ... and since there wasn't much out there yet, I took the plunge with my build and did a zillion DMM readings against the schematics to make sure I didn't do a blow-up-my-amp kind a thing. :D

:cheers:

Edited to fix crossed wires in responses. :D

As usual, my apologies for the confusion. If you wire the chassis to the shell of the
connector, it's redundant, as the shell connects to V- and also earth ground. The
Thermistor and lug/wire are there for the situation where the V- on the supply is
isolated.

just leave them Bstrdz wiggling in da breeze

:rofl:

now serious - redundancy is redundancy of redundancy

which means - Pa made some mess (in Revisions) to keep us Greedy Boyz triple secured

:clown:
